ELECTROMIGRATION INDUCED EDGE VOID DYNAMICS ON THE INTERCONNECT SURFACE

Four Fold Crystal Symmetry, {100} Planes in FCC


When the tilt angle is changed to 60°, the edge-void starts to decease by generating surface undulations in all directions. The amplitudes of these waves become more pronounce and their wave form becomes sawtooth-like shape having relative steep windward edge. It seems that there is steady translational motion of this wave package towards the cathode end with constant growth in amplitudes.
